It has been found tobedesirablein interioriconstruction to buildfvvallsentirely of plasgk ter, thus economizing in space. Aconstruo# tion of this character is illustrated` in my `co-,i`

However, in the h,constructi'on heretofore Y proposed,` a`Wood1jamb and trim has ,been

contemplated, and, 44due to 'thenarrow space,

Vthis has involvedsome difficulty.I Furthermore, in tire-proof buildings, it" isdesirable to eliminate wood portions ofthe frame .if

possible. I havey therefore devisedand herein describeda combinedbuckf, jamb andtrim u mum of labor andwithoutthe `use of ryn'yetal-` of simple form andv economical construction. Q lThe complete frame isgadaptedto .be assembled inthe shop andyinstalledv withaminif" Working appliances..-
